Butt fragment of greenish gray sandstone pestle, fine textured and hard; 
139.7 mm. long, 57.1 mm. diameter. Bulge of butt 14.2 mm. Purchased from 
Mr. José Ortega. Obtained by him from Burton Mound in 1901. 
Entire pestle of gray sandstone, 119 mm. long, 53.9 mm. diameter. Bulge of 
butt 12.7 mm. Some of the original tip end is still intact and shows asphalt 
stains on its surface. There is a large chip off the tip which extends 44.4 mm. 
down the side. Purchased from Mr. José Ortega. Obtained by him from 
Burton Mound in 1901. 
Entire pestle of greenish gray sandstone, 146 mm. long, 53.9 mm. diameter. 
Bulge of butt 12.7 mm. Thin surface scales are chipped off the butt. Pur- 
chased from Mr. José Ortega. Obtained by him from Burton Mound in 1901. 
Entire pestle of gray sandstone, somewhat friable, unique in shape since 
both ends are the same size and have equal bulge. At double ended pestle 
consisting of a straight shaft of stone, 252.4 mm. long, 74.6 mm. diameter. 
Bulge of the butts 12.7 mm. Purchased from Mr. José Ortega. Obtained by 
him from Burton Mound in 1901. 
LIMESTONE DISHES 
The considerable number of dishes or cups made by pecking out a 
roundish concavity in a slab or chunk of soft whitish limestone is 
probably to be explained by the occurrence of this material near at 
hand. Just what the vessels were used for is a matter of conjecture, 
none of them containing paint or other material, or even a stain. 
Several of them had not been used at all, judging from the fresh- 
looking pecking of their hollows. Their holding capacity is small. 
The stone is too soft to make the vessel of use for grinding, pounding, 
or even mashing. One of the specimens has a concavity on both 
sides. 
> 
Dish of yellowish limestone, 85.7 mm. long, 76.2 mm. wide, 44.4 mm. thick. 
The concavity is 38.1 mm diameter, 76.2 mm. deep. Edges rounded except at 
one end which is a square fracture. 
Dish of whitish, soft limestone, 152.4 mm. long, 95.2 mm. wide, 53.9 mm. 
thick. Concavity 76.2 mm, diameter, 12.7 mm deep. Edges rounded except 
one broken side. 
Dish of cream-colored limestone, very light in weight, 215.9 mm. diameter, 
179.3 mm. wide, 66.6 mm. thick. Edges rounded. Concavity 76.2 mm, diameter, 
17.4 mm. deep. The concavity is worn very smooth from use.
